Does your mouth stink in the morning? So does mine.
In fact, it stinks so much that the first thing I do in the morning is to rush for my toothbrush. If I accidentally swallow saliva before brushing, I'll experience serious stomach aches.
If for some reason I can't brush, I would have to spit more than a pregnant woman to avoid stomach aches. Also, I don't speak to anyone until I've brushed - not even to my parents. I just nod like a lizard.
